예

C#

ServerConnection conn = new ServerConnection();
conn.DatabaseName = "AdventureWorks2008R2";
SqlDataReader reader = conn.ExecuteReader("SELECT Name, CostRate FROM Production.Location");
while (reader.Read())
{
   string name = (string)reader["Name"];
   decimal cRate = (decimal)reader["CostRate"];
   Console.WriteLine(name + "(" + cRate + ")");
}
reader.Close();

PowerShell

$conn = new-object Microsoft.SqlServer.Management.Common.ServerConnection
$conn.DatabaseName = "AdventureWorks2008R2"
$reader = $conn.ExecuteReader("SELECT Name, CostRate FROM Production.Location")
while ($reader.Read())
{
   $name = $reader.GetValue(0);
   $cRate = $reader.GetValue(1);
   Write-Host $name,"(",$cRate,")"
}
$reader.Close()
